In a review of everything currently known about the topic, researchers recently developed a scientific model of how contemplative practices of various kinds may encourage better physical and psychological health. Published in Psychological Review, one of the flagship academic journals of the American Psychological Association, this new model advances our understanding of the adverse effects of stress and what can be done to combat it.
The researchers note there are four primary stress-related states we all experience: (1) acute stress (example: arguing with a spouse), (2) moderate threat (example: working), (3) rest (example: watching TV), and (4) deep rest (the least studied of the four, but most beneficial). Although many believe that rest is our baseline, default state, the scientists in this article suggest that, in the United States (and, by extension, in other developed countries), most adults now spend most of their daytime hours in moderate threat arousal, which drains of us of the restorative energy we need to function at our best. In fact, considerable research conducted over many decades demonstrates that this level of chronic stress contributes to various physical and psychological health problems ranging from heart disease to immune suppression, from chronic pain to depression. Individuals from marginalized groups seem particularly likely to experience this degree of toxic stress, helping to explain some of the health inequities we observe in certain groups such as people of color and individuals with poor economic resources.
Whereas acute stress and moderate threat cause sympathetic nervous system activity, deep rest is characterized by the dominance of the parasympathetic nervous system. The parasympathetic nervous system basically calms us. The researchers in the Psychological Review article further speculate that deep rest may be uniquely restorative at a cellular level. In this way – though there are surely limits – deep rest may be physically and psychologically “healing.”
Although there may be several activities that promote deep rest and enhance the body’s restorative capacity, most emphasized in the article is how contemplative practices may play a unique role. As noted by the authors, “contemplative practices are mind-body exercises that are intentionally practiced to work toward inner well-being, psychological flourishing, and deep connection with self, the world, or a higher power.” Examples of such practices include deep prayer, chanting, meditation, yoga, Tai Chi, and Qigong.
